The part targets applications like handheld instruments, portable medical devices, and IoT endpoints where a 1S LiFePO4 cell (3.5V full-charge voltage) is the energy store and USB VBUS is the primary charging source. ## Charge current and supply voltage — sizing the rail and thermal budget The maximum charge current is 1A, programmable via an external resistor — that sets the charging time for the cell and the thermal dissipation in the 10-WFDFN package. The over-voltage protection clamps the input to safe levels for the LiFePO4 cell.","metaTitle":"BQ25071DQCT LiFePO4 Battery Charger IC, USB Interface, 1A","metaDescription":"Texas Instruments BQ25071DQCT single-cell LiFePO4 charger IC with USB interface, 1A max charge current, 10.2V max supply, over-temp/over-voltage protection","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Interface":"USB","Mounting Type":"Surface Mount","Package / Case":"10-WFDFN Exposed Pad","Product Status":"Active","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Temperature, Over Voltage","Battery Chemistry":"Lithium Iron Phosphate","Current - Charging":"Constant - Programmable","Base Product Number":"BQ25071","Battery Pack Voltage":"3.5V","Charge Current - Max":"1A","Operating Temperature":"-40°C~85°C(TA)","Programmable Features":"-","Voltage - Supply (Max)":"10.2V","Supplier Device Package":"10-WSON (3x2)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.1700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/64ff155e47163c153aac6111a4271f3f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BQ25071DQCT/alternatives.json"},"ai":{"faq":[{"question":"Can BQ25071DQCT charge a 3.6V LiFePO4 cell?","answer":"Yes.
